Small BAseline Subset (SBAS) technique, developed by CNR -IREA, is a DInSAR approach allowing to detect Earth's surface deformation and to analyse their temporal evolution. To process SAR acquisitions using this technique large number of data is required and a sophisticate elaboration is necessary. A sequential code implementation leads to processing times that don't meet market constraints, very demanding in terms of processing time delivery. This work, in collaboration with CNR-IREA, demonstrates multi-threads potentiality to reduce processing time of SBAS chain, using multicore capabilities of new platforms in cluster environment. Development of a robust, efficient and flexible concurrent application for focusing module is described. © 2012 IEEE.

Main goal of this work has been to evaluate the accuracy of digital surface models (DEMs) extracted from in-track EROS-B high resolution satellite stereo imagery. The ability to capture high-resolution stereoscopic images can produce DEMs that are useful in different applications, especially environmental monitoring and mapping. This paper illustrates the results achieved during an experimental campaign for monitoring the Montaguto landslide area in Campania Region, Italy, through the use of stereo EROS-B imagery. The extraction of DEMs has been made using two commercial software: Leica Photogrammetry Suite (LPS) and PCI Geomatica, equipped with the orbital model of EROS-B satellite. The extracted DEMs were compared with those obtained by a LiDAR (Light Detection And Ranging) system and through classical aerial photogrammetry. Both software packages have highlighted an excellent quality in DEM extraction from EROS-B panchromatic images. Good results and an overall satisfactory performance are shown when a comparison with LiDAR data and the Regional Technical Chart (CTR) is done in terms of altitude differences and topographic profiles. © 2012 IEEE.

In this paper data from different sources have been used to monitor and characterize in a more extensive way a site of interest. The objective has been to implement a broad monitoring system through the combination of different data sources in order to control the whole area. Terrestrial surveying systems and aerial images have been combined with satellite remote sensing techniques in order to get a complete overview of the area stability and thermal characteristics in conjunction with geomorphological conditions and superficial water paths. Surveys conducted with a Leica TPS (Total Product Station) have been integrated with relieves from a traditional GPS (Global Positioning System) and a terrestrial LiDAR (Light Detection And Ranging) system to register land movements. Moreover satellite data have been use to get further information on the area in terms of morphological changes. Interesting observations have been deducted from the comparison among all the different data since land surface temperature retrievals and variations may be correlated to soil moisture and water exchange by showing that the proposed monitoring system performs correctly in taking under control deformation, terrain displacements, temperature and water surface modifications. © 2015 IEEE.
